UNITED STATES PATENT OFFICE,

HABRY THOMPSON, OF DEOATUR, INDIANA, ASSIGNOR TO HMSELF AND GEORGE W. MGCONNELL, OF SAME PLAGE I IMPROVEMENT lN TIRES.

Specification forming part of Letters Patent No. 170,'786, date& December 7, 1875; application filed November 13, 1875.

To all whom it may concm:

Be it known that I, HARRY THOMPSON, of Decatur, in the county of Adams and State of Indiana, have invented a new and lmproved Wheel-Tire, of which the following is a specification:

The invention consists of an outer and an inner rim or hand forming the tire, the inner one having an inwardly-prcjecting flange at each edge, to protect the sides of the felly, and to keep the tire on the wheel, and the outer one being to bind the inner over fast to the wheel, it being necessarily unconnected at the ends to apply it on account of the fianges. The outer on'e is kept on by a convex inner face, which shrinks into the concave outer face of the inner one.

Figure 1 is a section of the felly and tire, and Fig. 2 is a side elevation of a portion of a rin of the wheel.

Similar letters of reference indicate corresponding parts.

A is the onter rim of the tire, which has a convex inner face, and is Welded together like ordinary tires, making an endless` rim. B is the -inner rim, which has flanges D fitting the sides of the felly, and is unconnected at the ends E, and has a concave enter face to receive the outer rin and hold it firnly on the wheel. The outer. rim shrinks on the inner one, and draws it on the felly tightly, so that its fianges keep it in place.

Having thus described nyinvention, I clai n as new and desir'e to secure by Letters Patcnt- The combination of the open, concave, and flanged rim B, and the endless convex rin A, with 'the felly-rin O, suhstantially as specified.

HARRY THOMPSON.
